I haven't seen much evidence of that in this thread. No one has changed their minds on anything at all, suggesting no real intention of listening to other peoples views or perspectives. 'Evidence' has tended to be used to make a point rather than learn new things (and often comes from the same source).
I'm not saying that I'm any better of course, but lets be realistic here and call a spade a spade.
To be fair, I think this thread is holding up well and in comparison to the level of political discussion around and within the main parties election efforts to date, actually operates at a higher level.
What was refreshing yesterday was there was actually a coherent argument put forward for not having a referendum on Europe, the principle reasons being (i) firstly it is not necessary, we should be campaigning for change within not in/out,(ii) it would be highly disruptive regardless of the result (iii) the implications of a no result and (iv) an interesting observation that perhaps the general public are not best qualified to make the decision in the first place.
Now what would have been fascinating would have been a policy response from the Conservatives and others countering or agreeing with each of the above points.
Instead we got lazy (by design) journalism focusing on the Blair/Miliband relationship and the response from the PM that Blair was being contemptuous with the electorate.
The franchise operations which are the political parties today do not want in-depth analysis of their policies, they prefer sound bites and negative campaigning. I think this thread has risen above that.
